概要

Description

ATxmega64A1U-CUR is an AVR XMEGA microcontroller from Microchip/Atmel. It’s an 8/16-bit MCU with 64 KB of flash program memory and integrated USB 2.0 full‑speed device support, designed for USB-enabled embedded applications.
Key features (typical for this device family):
- Rich peripheral set: multiple USARTs, SPI, TWI/I2C, several timers, and a 12-bit ADC.
- Flexible I/O and clock options, plus advanced peripherals like the Event System and a Peripheral DMA Controller (PDCA) for efficient data transfer.
- Power-management modes suitable for low-power designs.
- Commercial-temperature/packaging variant indicated by the CUR suffix (verify exact package/pinout in the datasheet).
Development tools:
- Supported by Microchip Studio (formerly Atmel Studio), AVR-GCC, and MPLAB X.
- Commonly used in USB peripherals, data acquisition, and consumer/embedded control projects.
Note: The CUR suffix specifies packaging/temperature variant; check the datasheet for exact pin count, package type, and electrical details.

Equivalent

Equivalents depend on intent: there isn’t a published exact cross-reference for ATXMEGA64A1U-CUR. It’s part of the XMEGA A1U family (64 KB Flash, USB). Closest substitutes are other XMEGA A1U devices with the same memory/USB in a different package (e.g., ATxmega64A1U in another code) or similar 64 KB parts in the A1U family. For a guaranteed substitute, use Microchip’s cross-reference tool or specify required package and peripherals.
